Learn Red ? Fundamentals of Red

By: Ivo Balbaert

Overview of this book

A key problem of software development today is software bloat, where huge toolchains and development environments are needed in software coding and deployment. Red significantly reduces this bloat by offering a minimalist but complete toolchain. This is the first introductory book about it, and it will get you up and running with Red as quickly as possible. This book shows you how to write effective functions, reduce code redundancies, and improve code reuse. It will be helpful for new programmers who are starting out with Red to explore its wide and ever-growing package ecosystem and also for experienced developers who want to add Red to their skill set. The book presents the fundamentals of programming in Red and in-depth informative examples using a step-by-step approach. You will be taken through concepts and examples such as doing simple metaprogramming, functions, collections, GUI applications, and more. By the end of the book, you will be fully equipped to start your own projects in Red.

Running and compiling your first script

Experimenting in the REPL is fine for small code fragments and you should definitely use it, but soon you will want to keep your code in a file. Use your preferred code editor (or look at the last Development environments for writing Red section of this chapter for editors and IDEs with support for Red development) and type in the following text:

;-- see Chapter02/

Title: "Simple hello world script"
print "Hello Red World!"

Save the file as; .red is the extension for Red source code files.

The Red [ ] header block is mandatory; we'll see its purpose in the next chapter.
